Funcionamento de uma máquina a vapor

Machine Operation: Steam Engine

This section explains the operation of a steam engine, detailing the conversion of thermal energy into mechanical work through four main stages.

Boiler Heating and Steam Generation

• The water is heated in the boiler to a high temperature to generate steam, following the first law of thermodynamics.

Steam Inlet Valve

• High-pressure steam is released from the boiler to the cylinder, adhering to the second law of thermodynamics regarding expansion work.

Cylinder and Piston Action

• The steam pushes the piston, converting thermal energy into mechanical work based on the conservation of energy principle.

Steam Outlet Valve

• Steam is discharged from the cylinder to the condenser, cooling and condensing back into water, aligning with thermodynamic laws.
